断点调试和打印日志各有优点，下面我们来简要说说如何在程序中打印日志，在BCB6.0中实现。

//---------------------------------------------------------------------------#include <vcl.h>#pragma hdrstop#include <wtypes.h>#include <stdio.h>#include <fstream>#include <string>using namespace std;#include "Unit1.h"//---------------------------------------------------------------------------#pragma package(smart_init)#pragma resource "*.dfm"TForm1 *Form1;//---------------------------------------------------------------------------__fastcall TForm1::TForm1(TComponent* Owner)    : TForm(Owner){}//---------------------------------------------------------------------------void __fastcall TForm1::Button1Click(TObject *Sender){    SYSTEMTIME stCurTime = {
        0};    GetLocalTime(&stCurTime);    char szTime[128] = {
        0};    sprintf(szTime, "%d-%d-%d %d:%d:%d", stCurTime.wYear, stCurTime.wMonth, stCurTime.wDay, stCurTime.wHour, stCurTime.wMinute, stCurTime.wSecond);    char szLocation[1024] = {
        0};    sprintf(szLocation, "Function--->%s, Line: %d, File: %s", __FUNC__, __LINE__, __FILE__);    char buf[2048] = {
        0};    sprintf(buf, "%s %s", szTime, szLocation);    ofstream outfile("log.txt", ios::app);    outfile << buf << endl;}//---------------------------------------------------------------------------

结果，log.txt中为：

2013-11-9 10:42:57 Function--->TForm1::Button1Click, Line: 32, File: C:\\Documents and Settings\\Administrator\\hLآ\\bcbTest\\Unit1.cpp  
2013-11-9 10:42:59 Function--->TForm1::Button1Click, Line: 32, File: C:\\Documents and Settings\\Administrator\\hLآ\\bcbTest\\Unit1.cpp  
2013-11-9 10:43:0 Function--->TForm1::Button1Click, Line: 32, File: C:\\Documents and Settings\\Administrator\\hLآ\\bcbTest\\Unit1.cpp

实际上，上述只是打印了基本的信息，后续博文中会介绍如何打印其它需要打印的信息。
